Green Mediterranean Diet can Improve Heart Health (Study Finds) ๐Ÿ˜ƒ

Key Highlights

  • Cardiovascular diseases (CVDs) are the leading cause of death globally. [1]
  • Diet plays an important role in Cardiovascular health. [2]
  • A new study shows that green Mediterranean diet can improve heart health. [3]

Before starting, let me tell you that after an overnight fast, our body increase a specific hormone production from the stomach called ghrelin or hunger hormone.

Ghrelin is also increases after weight loss.

According to this new study published in The Journal of Clinical Endocrinology and Metabolism, ghrelin may help reduce abdominal visceral fat and improve the body’s sensitivity to insulin.

Another interesting fact of this study is researchers proposed a new type of Mediterranean diet called green-Mediterranean diet. 

It includes green leafy vegetable called mankai or duckweed and green tea and omitted red meat.

Researchers found that green-Mediterranean diet can double the production of fasting ghrelin after weight loss and an overnight fast, compared to traditional Mediterranean diet or a healthy, balanced diet.

They suggest that green-Mediterranean diet have additional cardio metabolic benefits.

How was the Research Done?

For this study, researchers included 294 participants with abdominal obesity or dyslipidemia โ€” a condition with abnormally elevated cholesterol or fats in the blood.

Researchers randomly assigned everyone to one of three diet: general healthy diet, traditional Mediterranean diet and green-Mediterranean diet and measured their fasting ghrelin levels over 18 months.

All participants, who were selected from an isolated workplace, received controlled lunches, were instructed to exercise, and were provided with a gym membership.

What is the Result of this Study?

Individuals who followed the green Mediterranean diet, had twice as high fasting ghrelin levels as those who followed a traditional Mediterranean diet, despite similar caloric restriction and weight loss.

Mankai or Duckweed, Mediterranean Diet can Improve Heart Health
Mankai is an ancient green that contains complete protein.

What did the Researchers say?

The lead study author Iris Shai of Ben-Gurion University of the Negev in Israel and Harvard T.H. Chan School of Public Health in the United States said that “the results suggest that fasting ghrelin levels may be a valuable indicator of cardiometabolic health after weight loss,”

โ€œElevated fasting ghrelin levels may help explain why the green Mediterranean diet optimized the microbiome, reduced liver fat and improved cardio metabolic health more than the other diets in our study,โ€ Shai says.

“The results of our study suggest that fasting ghrelin is an essential hormonal factor in the recovery of diet-associated insulin sensitivity and regression of visceral adiposity, or belly fat reduction,โ€ adds the paper’s first author, Gal Tsaban, a researcher and cardiologist at Ben-Gurion University of the Negev and Soroka University Medical Center, both in Israel.

He notes that โ€œthe differential and diet-specific response in elevating fasting ghrelin levels may suggest another mechanism in which different dietary regimens, such as the Mediterranean-green diet, reduce cardio metabolic riskโ€.

The Final Word

According to WHO, cardiovascular diseases are the leading cause of death globally.

This study proposed a new diet called green Mediterranean diet which can support heart health after weight loss.
